Used extensively as a solvent in nuclear magnetic resonance (NMR) spectroscopy due to its deuterated form, which provides a clear and stable signal without interfering with the analysis of other compounds. It is particularly valuable in studies involving organic molecules, where it helps in identifying and characterizing molecular structures. Additionally, it serves as a solvent in research and development for synthesizing and testing new chemical compounds, ensuring minimal interference from hydrogen signals. Its application is also found in the pharmaceutical industry for drug development and quality control processes.
